Last week, I got the Service Engine Soon light on my dash. It was still running fine, so I kept driving it, but finally got around to hooking up INPA to see the fault codes. Here is what I have:
94 Fehler Sekundaerluftmassenmesser (I believe this is secondary MAF, had this one before on an extremely cold day)
95 SAV oder SA-Schlauch blockiert (don't know anything about this one, but the last part translates to 'hose blocked')
97 SA-Durchsatz zu gering (translates to 'throughput too low')
Does anyone know about these errors? Are they all related to the secondary air pump system? I picked up some MAF cleaner the other day and I just ordered a new secondary air injection pump filter since it is cheap (11727534722). I haven't used the MAF cleaner on either MAF yet. After clearing the codes last night, I started it and the SES light was gone. Then I started it later and it started real rough, SES came back on. I shut it off, restarted, and it ran a little better, but something doesn't seem right now. Going to check codes again shortly, but I bet all 3 are back.
Below you can see multiple occurrences on these faults and more data:
